こノ考案は、オートバイ等に用いる小型エンジンのエア
クリーナの吸気騒音低減装置に関する。[Detailed Description of the Invention] This invention relates to an intake noise reduction device for an air cleaner of a small engine used in a motorcycle or the like.
クリーナを装着する必要があって、場所の制約を大きく
受け、騒音を少くすることがむつかしい。It is necessary to attach a cleaner, which greatly limits the space and makes it difficult to reduce noise.
この考案はかかる点に鑑み、小さいエアクリーナで有効
に吸気騒音が低減できるように改善したもので、以下図
面に示す本考案の実施例について説明する。In view of these points, this invention has been improved so that intake noise can be effectively reduced with a small air cleaner.The following describes an embodiment of the invention shown in the drawings.

、出口２はエンジンの吸入管４に連結する。FIGS. 1 and 2 show an embodiment of the present invention, in which a cleaner body 1 has a housing shape with an appropriate volume, and a cleaner element 3 is installed inside an outlet 2 to remove dust. The outlet 2 is connected to the intake pipe 4 of the engine.
クリーナボデー１は出口２と反対側の一側に短い吸気管
５を設ける。The cleaner body 1 is provided with a short intake pipe 5 on one side opposite to the outlet 2.
そして吸気管５の周りに渦巻状の干渉管６を設け、干渉
管６の内端は吸気管５を包むように二重管にして開口Ｉ
する。A spiral interference pipe 6 is provided around the intake pipe 5, and the inner end of the interference pipe 6 is made into a double pipe so as to wrap around the intake pipe 5.
do.
干渉管６の外端は、クリーナボデー１の内壁に沿って半
径方向に延び吸気管入口９部に開口する誘導管８に連通
させる。The outer end of the interference pipe 6 is communicated with a guide pipe 8 that extends radially along the inner wall of the cleaner body 1 and opens at the intake pipe inlet 9.
第３図は本考案の実施例を示すもので、第１図及び第２

くに開口させたものである。Figure 3 shows an embodiment of the present invention;
In addition to what is shown in the figure, a second guide pipe 11 is communicated in the middle of the interference pipe 6, and the second guide pipe 11 is opened near the intake pipe inlet 9 section.
作用について説明する。The effect will be explained.
クリーナボデー１は膨張室として、主として高周波域の
騒音を消音する。The cleaner body 1 serves as an expansion chamber and mainly muffles noise in the high frequency range.
そして吸気は短い吸気管５と長い干渉管６０両方から吸
入される。Intake air is taken in from both the short intake pipe 5 and the long interference pipe 60.
干渉管６は発生する低周波域の騒音に合せて長さを設定
し、ピークが複数の場合は第二誘導管１１を設けること
によって所定の低周波域の騒音を干渉によって低減でき
る。The length of the interference tube 6 is set according to the noise in the low frequency range that is generated, and when there are multiple peaks, the second guide tube 11 is provided, so that the noise in the predetermined low frequency range can be reduced by interference.
しかも短い吸気管５も開口しているので吸気抵抗も大き
くならず、互に干渉させることができる。Moreover, since the short intake pipe 5 is also open, the intake resistance does not become large and they can interfere with each other.
以上説明したように、この考案はクリーナボデーの一側

口部に開口する誘導管に連通させたので、上記吸気管入
口部における音が、通路が短かい吸気管と、誘導管およ
び干渉管からなる長い通路とに分れ、そハらが大気開放
時に一つにオと會り互いに干渉さ力、吸気音が効果的に
減衰される。As explained above, this invention has a short intake pipe protruding from one side of the cleaner body, a spiral interference pipe around the intake pipe, and a double-layered structure with the inner end of the interference pipe wrapped around the intake pipe. Since the outer end of the interference pipe is communicated with the guide pipe that opens at the intake pipe inlet of the cleaner body, the sound at the intake pipe inlet is transmitted through the intake pipe with a short passage, the guide pipe and the guide pipe. It is divided into a long passage consisting of an interference tube, and when it is opened to the atmosphere, it meets with the O, effectively attenuating the forces and intake noise that interfere with each other.
しかも上記干渉管は渦巻状に形成されでいることにより
比較的場所を要することなく十分長い管路が構成され、
波長の長い低周波域の騒音を十分減衰させることができ
、吸気騒音の低減が図れる。Moreover, since the interference tube is formed in a spiral shape, a sufficiently long pipe can be constructed without requiring a relatively large space.
Noise in a low frequency range with a long wavelength can be sufficiently attenuated, and intake noise can be reduced.
しかも上述のように短かい吸気管も併設しであるので吸
気抵抗も少くできる。Furthermore, as mentioned above, since a short intake pipe is also provided, intake resistance can be reduced.
